Gear change needed if UNlocked?

Hey Guys,

Ive been running my XO-1 for almost a week now, and I just love it. Ive ran it on 4S at first, then I ran it on 5S and this weekend I ran it at 6S (locked)...

If I UNlock it, and I only want to try to go maybe 70 to 75 MPH - do I need to do a gear change or can I run the XO-1 unlocked with the stock gear and not have any issues? Again, I dont care to do 100MPH - I just dont want to mess with the gears, because I do alot of drifting, and not just high speed runs.

I honestly do not know, a friend gave it to me. One of those random loose parts in the bottom of the tool box. It is black with a white "24" stamped on it, no manufacturer is listed. There are many many many companies that make gears. You need a mod 1 pinion gear with a 5mm opening for the motor shaft. From what I've found most all 1/8 pinions for buggies and monster trucks will work. Make sure it is a mod 1 though, the mod .8 will not work.

As long as it has a 5mm motor shaft opening and a "mod 1" or "1 mod" tooth size you should be good to go. Unfortunately I cannot verify specific non-Traxxas items or brands that will or will not work.

I can note that a 5mm-bore Integy pinion that a friend bought for his Summit was not bored 5mm all the way through. It tapered to somewhere between 4.8 & 4.9mm and therefore would not fit on a 5mm motor shaft. I'd avoid them.
